Carbon Ribbon SflPply
Mounted to a bracket on the left-side-frame are
the take-up spool assembly and the feed mechanism
(Figure 35). The bracket is inclined for easier re-
moval of the used ribbon. Take-up action is accom-
plished through a friction drive-gear attached to the
power-roll pulley and engaging gear teeth on the in-
side flange of the take-up spool.
The take-up spool fits into a slot in the feed bracket
so hinged that the gears may be disengaged and the
spool removed. The two halves of the spool pull
apart for removal of the used ribbon. A spring latch
locks the bracket in the closed position and releases
it whenever the release lever is operated to disengage
the pressure rollers.
